Did you know that thawing permafrost is impacting Arctic livelihoods already today?

Did you know that thawing permafrost is impacting Arctic livelihoods already today?

Would you like to join me on a little trip up North today? We will be visiting a small community in the Canadian high Arctic – a community built on permafrost ground. This sounds pretty cool in the first place, but brings along quite a few challenges that most of us probably do not have to think about. Let me introduce you to Tuktoyaktuk, the community that is endangered to fall into the sea ...[Read More]

End-of-the-year special: this year’s Cryoblog

End-of-the-year special: this year’s Cryoblog

So this is the last post in 2022 for our blog. We have decided that this time, the topic will not be another exciting story about the science of ice and cold in their various forms. This time we are talking about the blog itself, so a kind of meta-post to take stock and understand a little better how our blog works, what it is about, and who our main authors are. To this purpose, we asked all the ...[Read More]

Fun Cryo Facts – Don’t eat brown snow

Scientist are curious people and we all know that the best discoveries happen by chance, so we always keep our eyes open for the unusual, the new, and the weird things in life. Especially, when we are out in the Arctic doing field work and find unknown brown layers… An unexpected discovery We were out in the Arctic, somewhere Northeast of Svalbard. It was a sunny day and we had just docked t ...[Read More]

A little guide to find your way through the Cryo-Jungle?

Are you starting your studies in cryospheric sciences, or are coming into our field from another subject? If so, you may have unsuspectingly waded into a (very thick) soup of acronyms! Don’t fret–here is your “one stop shop” that tells you where to look for more information! Early Career Organisations Unless you’re fortunate enough to be working in a polar-oriented institute (some of our previous ...[Read More]

Did you know that snow is hot?

Did you know that snow is hot?

When I was a student, Martin told me matter-of-factly that snow is hot. I probably looked as baffled as I felt (and you are probably doing the same). Were we talking about the same thing? Continue reading to discover why snow is hot! Discovering that snow is hot So why is snow hot? Most snow under Earth’s environmental conditions has a homologous temperature Th close to 1. The homologous temperatu ...[Read More]

Cryo History – Extent of South Georgia Glaciation during the Last Glacial Maximum

Cryo History – Extent of South Georgia Glaciation during the Last Glacial Maximum

There has been considerable disagreement amongst researchers concerning the extent of South Georgia’s ice sheet during the Last Glacial Maximum (LGM). The sub-Antarctic islands (those below the polar front) may have been completely glaciated during previous glacials, and the last largest extent of the South Georgia ice sheet was during the LGM, about 21,000 years ago. But glaciologists don’t agree ...[Read More]

More pancakes in the future!

More pancakes in the future – that sounds like a very good New Year’s Eve resolution for Sunday brunches, but it could also be a development of the most tasty looking sea ice shape in the Arctic. Let’s find out more! Arctic Sea Ice The growth and melt of Arctic sea ice follows a seasonal cycle. In the springtime, under the midnight sun, the sea ice begins to melt until it reaches its m ...[Read More]

Climate change and cryosphere – A wetter future for the Arctic

Climate change and cryosphere – A wetter future for the Arctic

The latest climate models show that Arctic precipitation is changing more rapidly than previously projected with an earlier transition to a rainfall-dominated precipitation. This rapid change in precipitation will have huge implications for the Arctic ecosystem as well as those who live within the region. Arctic precipitation change, why is it so important? The rapid change in Arctic climate, from ...[Read More]

The Polar Amplifier

The Polar Amplifier

It’s no secret that the Arctic is warming faster than the rest of the planet, but why? Polar Amplification (often called Arctic Amplification) is the mechanism at play. In this week’s blog, we find out about its origins and why it happens. Early Discoveries In 1969, Russian scientist Mikhail Budyko and US scientist William Sellers discovered independently that the increase in greenhouse gases comb ...[Read More]

The Norwegian Polar Institute

It is a pleasure for the EGU Cryoblog team to present a new post category: Cryo-institutes around the world! There are many institutes working on cryosphere-related research spread around the world. The aim of this new category is to highlight the cool research that is carried out at these institutes, showing off our multi-faceted cryo-related science. In this opening post, Ashley Morris will pres ...[Read More]
